I need a stereo volume control. can you please tell me what parts do I need to buy?

What type of stereo volume control?

If you mean a motorised pot, you can use the Remote1 board and an RK27 or RK16 pot. There are also relay and PGA2310 based attenuators available.

2 questions:

1. with the pga2310-based volume control, how do I change the volume?

2. with relvol1 with control, I assume the control is built-in. but if I buy relvol3, I would need a control circuit. is this right?

thanks for the reply.

For just a volume control (no input selector etc.), you can use the VolControl1, 2 or 3 (different displays).

Yes. And in the RelVol3 case, you could use the VolControl boards also.

the buffer on the pga2130-based volume control uses opa2134. can this be changed to dual-opa627bp (using an adapter)?


when you say "no buffer" (on the pricelist for the chipvol1), do you mean:

the parts for the buffer have been removed OR
the kit does not include the opa2134?

thank you.

Yes, you can use any op. amps. as long as they are unity gain stable.

Both I guess. None of the parts for the burffer stage (chip, resistors, caps) are included, and you connect the input signal to the PGA chip directly.

what's the dimension for relvol1 with built-in control? also is the pot in the signal path?

The size is 75*93mm. The "pot" isn't in the signal path, as there isn't one. It's a digital encoder.

that brought another question: Relvol1 with built-in control can replace a stepped attenuator of the same impedance. is this assumption correct?
